STAMPING MACHINE.

Application led November 6, 1923, Serial No. 673,164, and in NorwayNovember 7, 1922.

The present invention relates to a machine for stamping, impressing orprinting of characters, designs, patterns, ornaments &c. on metals,stone, wood, porcelain, paper &c.

One object of the invention is to provide a machine of the type referredto, in which the stamps or matrices used for the stamp ing, impressingor printing may be easily positioned accurately over the desired spot ofthe plate or the like to the stamped &c. by means of the said machine.

Another obj ect is to provide means whereby the stamping, impressing orprinting may take place in any desired direction on the plate or like inquestion. y Still another object is to provide means whereby thedistance between the characters which are impressed or printed may beeasily adjusted, and also to provide means whereby the correct distancebetween adjacent characters is almost automatically chosen,notwithstanding the fact that alphabets &c. having characters ofdifferent types and size may be used in one and the same machine. i

i The invention also includes a special type of stamps or matrices to beused in connection with the machine referred to.

' Further features will appear. from the following description andclaims.

The accompanying drawings show one constructional form of a machineaccording to the invention, which machine is espe cially adapted forprinting map designs.

lVith reference to Figs. land 2 the legs 1 support a casing 2, the uppervside of which is provided with longitudinal V-shaped grooves 3, whichare adapted to receive andV guide correspondinglyV shaped ribs 4 on asliding table 5. The said table is at the upper side thereof providedwith a circular groove 6, which receives a rib or projection 7 on aworking table 7, which is mounted on the table 5 and may be turnedthereupon. The movement of the table 7l may kbe obtained by means of ahand wheel 8, which through a shaft 9 journalled in the table 5 andl aworm 11 acts upon a worm wheel 10, which is secured to the lower sideofthe table 7.

The tables 5 and 71may be imparted translatory movements on the casing 2by means of a hand wheel 12, the shaft 13 of which is journalled in thecasing 2 and carries a gear 14 that meshes with a rack 15 arranged atthe lower side of the table-5.

To each sideof the casing 2 are, in a suitable manner, secured brackets16, 17 whichV The shaft 13 carriesatthe endl thereof a I sprocket wheel23 which .may be driven,

through a chain 24 from a'sprocket wheel 25 carried on a shaft 26, whichis journalled in supports 27 and 28 mounted on the beam 18. The Ashaft26 is provided with a longii tudinal wedge groove 29, which receives acorrespondingly shaped wedge on a sleeve 30 provided with a hand wheel31. The sleeve 30 is rotatably mounted ina bracket 32 secured to thesupport 19, and thus the sleeve 30 and the hand wheel 31 will accompanythe support 19 when the same is moved along` the beam 13. When the handwheel 31 is rotated, the sleeve 30 will turn the shaft 26, which in itsturn rotates the sprocket 25, and thus, through chain 24 and sprocket23, i'otates the shaft 13, which latter, by means of the gear 11i andthe rack 15, moves the table either in one direction or the other.

The support 19 is provided with a fixed ring member 33. Figs. 3 and 9 onwhich is rotatably mounted ya ring that carries the stamps. The lastmentioned'ring is kept in Y place on the ring member 33 by means oitclamps 34 and screws 35. On the support are ,also formed brackets 36 and3. respectively, the bracket 36 acting as a guide for a'pin 33, the topend of which carries a roller 39, and the lower end of which is formedas or secured `to a press plunger --O, which penetrates into avertically arranged aperture in the ring member 33. Between the ringmember 33 and a disc 4:1 on the press plunger, is mounted a helicalspringl 12, which acts to keep the press plunger in its upper position.The press plunger may be lowered by means of a lever i3 which ispivo-tally mounted on the bracket 37 and provided wih an eccentricportion all, which,

when the lever 4:3 is turned to the lett (Fig. '3), acts against theroller 39, thereby press-- ino' the same andaccordingh also the n a Qplunger 40, downward.

It should be noted however that the means for moving the press plungerdownward may be of any other suitable type than those here described,which are shown 'only by way of example. hus press screws, levers Sac.may be used.

Figs. 10 and 11 illustrate another manner of mounting the stamp ring onthe support 19. 1n a projection 45 onv the support 19 is mountedavertically arranged shaftli. held in place by means of a nut 47. Theshaft .t6 carries a horizontally arranged disc or ring member, in whichthe stamps are ar- CTI Vand alsoy the pin38.

ranged. The lever 43, which is providffi with the eccentric portion t,is pivotally mounted in ribsli arranged 4on the projection 45, whichribs are also provided with vertical slots 19 that receive the pin 5()which carries the roller 39, thus yguiding' the same A horizontal rib 51situated between the ribs 13, hasa vertical hole which guides the lowerportion of the press plunger 40. In order that thepress Yplungerithifdesired, may be lowered without using the lever 43, the rib 51 isprovided withA a vertical s lot through whichA extends a finger 52,which is secured to theplunger andk Lmay bepressed upon to lower theplunger.

ring which carries the stamps, these latter being radially movable asshown in Fig. 8. rllie ring rdesignated generally at 100 is made up ofthree distinct rings 53, 54 and 55 respectively each provided withprojections 56 or grooves, to adjust the position of the rings withrespect to each other. These three rings are provided with radial holes5'? to receive the stamps 53.` The diameter of the hole of the middlering 54 is somewhat greater, thusproviding space orthe arrangen'ient or'a helical spring 59 around the stamp. The lower end oi the spring 59acts against the ring and the upper endV thereof against a pin 60,ywhich is passed through the stamp 53. The ends of the pin 60 extend intovertical slots 61 arranged in the hole, whereby the stamp 58 isprevented from turning` or rotating in the hole. Y

1n Fig. 13 is shown a section through a stamp ring when arrangedhorizontally.

The ring consists ot two separate parts 62.

and 63, which are provided with holes 57i.

lThe lower part of the hole in the part 62 has a greater diameter thanthe rest of the hole, to provide space for the spring 59 and transversekthe pin 60. In this case the stamp is prevented from turing'by means orpa 1Woodruf wedge 60', which goes into corresponding wedge groove`arranged in the side of the hole 57 in the part 63.

The stamp rings are arranged to receive an alphabet of capital lettersand one alpliabet ot small letters andv further the ring Y is providedin line with each stamp A58, with a inarkation stating the letter,number or character of the stamp in question, andalso with a markationline which, when a stamp 53 isplaced directly below the press plunger40, corresponds with a inarkation on the projection 33. Thus the desiredvstamp may readily be brought in correct posi-tion below the plunge :lnorder to make it more easy 'for the operator to move the stamp ring bymeans of his lingers, thesaid ring maybe provided with suitable cavitiesor be knurled in well known manner.

ln each stamp ring is also arranged a special Astamp ,or pin 611 (Figs.14h15) the lower end of which is shaped to form a line point. Thisstamp, theobject of which will be described later, and which will bedenoted as adjusting pin, is eccentrically mounted and longitudinallyvmovable in a sleeve 65, which latter is mounted eccentrically androtatably in a sleeve 66, the lastnamed sleeve being rotatable in thestamp ring. The sleeves 65 and 66 are, both of them, at the lower endsthereof, provided with flanges 68 and 67 respectively. The peripheriesof the said flanges are provided with holes, and by placing a suitablepin or key in these holes the sleeves may be turned, whereby theposition of the adjusting pin 64 may be changed in relation to the axisof the opening 57. The upper part of the pin 64 carries a head 69 andbetween this head and the sleeve 65 is placed a helical spring 70, whichpresses the pin 64 upwardly or inwardly. The holes in the flanges 67 and68 are made accessible, and the light is given access to the pin 64, bycutting away suitable portions of the ring members 54 and 55 adr'acentthe lower end of the pin 64.

he support 19 and the stamp ring must be sufficiently displacedlaterally for stamping of the next letter in the word to be stamped. Tothis effect the end of the shaft 21 carries a gear 71l (Figs. 3 and'4),which through a gear 72, adjustably mounted on a member 73, act-s upon agear 74 rotatable on a shaft 75 that is journalled in a bracket securedto the frame 16. On the shaft 75 is also pivotally mounted an arm 77,which carries a spring pressed pawl 78, which is provided with a handle79 and may mesh with the gear 74.

On the frame 16 is demountably secured a circular shell or hoop 80, thecentre of which coincides with the centre of the shaft. In this hoop 80,and vertically to the longitudinal direction of the arm 77, there arearranged pins 82 having heads 81, which pins through the action ofsprings 83 are normally held v'within the hoop 80. When it is desired,to

displace the support 19 a certain distance, that pin 82 whichcorresponds to such distance (indicated by the numbers on the hoop 80)is pressed toward right (Fig. 4) ragainst the action of the spring 83,whereby the arm 77 when moved to move the gear 74, willy abut with itsabutment 84 against the said pin 82. Thus the movement of the pawl 78 islimited to that number of teeth on the gear 74, which are necessary toimpart the desired movement to the shaft 21 and thereby to the support19. If, in some instances, the displacement of the support determined bythe said pins 82, is to be increased'or decreased, the gear 71 may beremoved and replaced by a smaller or a greater gear. Very longdisplacements of the support 19, which for instance occur during theinitial adjust-l ing of the same in the correct position over the'table, are carried out by first displacing the gear 71 on the shaft soas to bring the same out of mesh with thegear 72, whereupon the shaft 21is turned by means of a vcrank 86 withv a handle 85, carried at the endof the shaft 21.

In Figs. 5 and 6 is shown a modification of the means for .displacementof the support 19. The hoop 8O is provided along its periphery, withnotches 87 vwhich coact with a spring pressed pawl 89 that is providedwith a handle 88.2 The said pawl is situated in an arm 90 mounted on theshaft 21, which arm also has an extension 91 that eX- tends closely overthe periphery of a ratchet wheel 92 securedto the shaft 21. shaft`21 isalso pivotally mounted'an arm 93 that carries a spring pressed pawl 95for coaction with the ratchet wheel. 92. On the beam 18 is in a suitableway secured a bracket 96 which limits ythe rearward movement of the arm93.

iVhen the support 19 is to be. displaced by means of this mechanism, thearm 9() with its pawl 89, is swungdown to the proper notch in the hoop80. The extension 91 thus becomes placed over a certain spot of theratchet wheel 92, and when the arm 93 is swung forward the pawl 95 will,by reasonof the wedge shaped section of the extension 91, be moved on toand on the outer side of the said extension. Nhen the pawl has thusengaged the extension, the arm 93 'is swung backward',and the pawl willslide down the extension and engage the ratchet' wheel 92. Thus theact-ion of the pawl 95 is limited t0 the desired number of teeth.v f

IOn rthe y In Fig. 7 is shown still another modiv fication of the.mechanism for displacing of the support v19. Here the arm 90 is omitted,lonly one arm v'being used. AThe arin 93 carries a plate spring'97 thefree end of which is V-shaped, as are also the Ynotches 87 in the hoop80. YWlhen the arm the support may easily be displaced a' corre-Lsponding number of differentf distances,

wlieiitlie machine is usedy for printing of, say, a name. This isachieved by proper arrangementof the notches 87, so that when the arm 93is moved toV any one' ofthe said notches and then back to itsvrearposition, .the ratchet wheel and accordingly also; the shaft 21vwill be turned'to' such 'an' extent that the'supportvis displaced adistance which corresponds to lthef=width of that class of letter whichthe said notch represents.

lf the pins V82 4, 6 and 7) the ring member" which carries the stumpsmayf'also-be provided, directly below the letters which indicate thedifferent stamps, with numerals that' state to lwhich l Y or notches87are designated Vby `the numbers 197 for instance (see Figs.-

class as to width) the letter in questionbelongs.

(Figs. 9 and 10). Thus, when a letter is placed below the press piston40, it is also at the same time seen how far the arm 93 is to be movedover the hoop 80 in v4order that the support 19 shall be displaced thecorrect distance to ensure that the letter, when stamped ory printed,shall get the lcorrectI position in vrelation to the letter last stampedor printed.

For alphabets having letters ot different types and sizes, the classarrangement (the notches or pins) oi' the hoop 8O must be For thisreason the hoop 8O is made demountable, so that when a new stamp ring isinserted, also the corresponding` hoop S may be replaced for thatpreviously used. To avoid mistakes the ditferent stamp rings/and theircorresponding hoops may be provided with corresponding designa-tioncharacters. rlhe size of each class on the hoop 8O includes, ot course,not only the actual width of the class of letters in question, but alsothe distance which should be obtained between adjacent letters whenAprinted or stamped.

In ordei to be able to obtain, ii desired, a greater and smallerdistance between adjacent characters, special hoops 8() may beused, voreach hoop SO may be provided with a special notch or pin so arrangedthat the same in eachy case will add or substract) a certain distance to(from) the normal one determined by the usual notches or pins.

The adjusting pin 64 shown in Figs. 14

and serves to provide a vmeans whereby' the first letter of a word to beprinted will be printed in exactly the desiredY position. The point ofthe pin 64 is so situated that it exactly corresponds with the.intersection of say the right side of each letter space and theimaginary base line thereof. During the adjusting of the support ot themachine, in order Ato place the support in correct relation to the pieceto be printed upon, the said support is adjusted until the Y,

and then adjust the pin 64 to correct position in the stamp ring, byturning theV sleeves 65 and 66 until the point thereof when depressed,will cover the point of the section mentioned above.

In order that each character shall be stamped to an equal depth, eachstamp 58 (Figs. 16 and 17) carries at the end thereof, the charactermatrice in the shape of `an eX.- teiision on the stamp. Thus the stamprod 58 proper will abut against the plate in which the character isimpressed, and limit the movement of the stamp, no matter which is thepressure exerted on the ypress piston.
